BOTTLE-STOPPER COVER.

SPECIFICATION forming part of Letters Patent No. 372,892, dated November 8, 1887.

Serial No. 231,802. (ModeL) To all whom it may concern.-

Be it known that I, THOMAS C. BUNTING, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvements in Bottle Stopper Covers, of whichthe following is such a full, exact, and clear specification as to enable any one to make and use the same.

The object of my invention is to provide a device for protecting the lips and necks of hottles for medicines and chemicals from an accumulation of dust, and also to protect and shield the stopper from extraneous contact when out of the bottle. I attain this object by means of the cover illustrated in the accompanying drawings, in which- Figure 1 shows a section of the cover as attached to a stopper of the form ordinarily used for chemicals. Fig. 2 shows an elevation of a cover detached from a stopper, and Figs. 3 and 4 show the cover applied to various forms of stoppers.

Similar letters refer to similar parts .in all the figures.

The stopper-cover is made in the form of a frustnm of a cone of any suitable material, the seam overlapping at A A, and being held loosely in contact by the single rivet B. The upper part of the conical frustum has formed in it a groove, 0 0, this groove curving inward. The upper edge of the cover is also curved inward, as shown at D D, forming a flange, and between the flange D D and the groove 0 0 there is thus formed a channel, E, which receives the head of the stopper F. The elasticity of the metallic cover causes the channel E to hold the stopper F with sufficient The cover is always made longer than the stopper itself, so that when the stopper and cover are set down upon a table or elsewhere the lower part of the cover will prevent the end of the stopper from coming into contact with thetahle, and thus prevent any dust or foreign matter from being introduced into the bottle when the stopper is replaced. In this Way a very frequent source of contamination to delicate materials will be prevented. Vhen the stopper is in the bottle, the cover protects the lip of the bottle from dust and avoids the coating of dust and medicine which otherwise often occurs.

It is evident that the cover must not be soldered or otherwise rigidly fastened together, as it would then be very difficult to attach or remove.

I am aware that covers have been used in connection with bottle-stoppers, being either made in one piece with the stopper or otherwise rigidly attached, and I do not desire to claim such acover, broadly.

\Vhat I do claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of a stopper and open tube. the said tube being closed at one end by ,the head of the stopper, around whichsaid tube is removably attached and from which it extends downward outside of and covering the neck of the bottle, the lower edge of said tube projecting below the lower end of stopper, substantially as described, and for the purpose set forth.

2. A stopper-cover composed of a conical tube of sheet metal grooved at the top to re ceive the head of thestopper and held together by a single rivet, so as to be readily detachable from the stopper by the application of a moderate pressure.
